MACHINE FOR BEATING OUT SHOE-UPPERSQ To all whom, it may concern:

Be it known that I, VVILLIAM GounoN, a citizen of the United States,residing at Boston, in the county of Suifolk and State of Massachusetts,have invented certain new and useful Improvements in Machines forBeating Out Shoe-Uppers; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as i willenable others skilled in the art to which it appertains to make and usethe same.

The present invention relates to a machine for beating out shoe uppers.

In the manufacture of shoes it is desirable that the lower edge of theupper be pulled tightly and smoothly over the edge of the heel portionof the insole and be pressed closely against the surface of the insolein order that the cutsole may fit close to the upper and the upperpresent a neat and finished appearance in the completed shoe.

The object. of the present invention is to provide a machine by whichthese operations can be performed quickly and in a satisfactory manner.

In accordance with the present invention the operation of pressing thelower edge of the upper closely against the surface of the insole isperformed by means of a tool which acts to deliver a series of blowsupon the lower edge of the upper and beat it out upon the insole. Thisbeating action of the tool not only presses the upper closely againstthe surface of the insole, but also forms a permanent sharp bend in theupper at ,the

edge of the insole so that this portion of the upper presents a neat andfinished appearance in the completed shoe. In the illustrated embodimentof the invention hereinafter described a rotary tool is employed,provided with a series of heaters which deliver a series of blows uponthe lower edge of the upper and at the same time exert a rubbing orwiping action upon the upper from the edge of the insole toward themedial line of the sole, which tends to smooth out the upper and polishthe upper at the edge of the insole as well as to draw the upper towardthe medial line of the sole.

In the machine hereinafter described as embodying the preferred form ofthe inven tion two rotary tools are provided arranged to actrespectively upon the shoe upper at opposite sides of the shoe, eachtool being provided with a series of beaters. By this Specification ofLetters Patent.

Application filed March 23, 1905.

Patented June 25, 1912. Serial No. 251,618.

arrangement of the beating out tools two series of rotating heaters areprovided which act simultaneously to beat out the lower edge of theupper upon the insole at opposite sides of the shoe, and the provisionof these heaters is considered to constitute a feature of the inventionregardless of the specific manner in which the heaters are supported andactuated. To produce the best results, however, it is desirable that thebeaters should be so mounted as to be capable of accommodatingthemselves to the shape of the sole being operated upon, andparticularly to the varying curvatures of the edge of the sole, and inthe preferred embodiment of the invention the heaters are so mounted.

The features of invention above referred to may be embodied in a machinein which the beating out tool or tools are alone relied upon to beat outthe lower edge of the upper and impart a finished appearance to theupper at the point where it bends over the edge of the insole. In thepreferred embodiment of the invention, however, two upper finishingtools are also provided arranged to act upon the upper at the edge ofthe insole. These tools are yieldingly pressed toward each other and arethus allowed to automatically conform to the varying curvatures of theedge of the sole. \Vhile these tools cooperate with the beating outtools in smoothing out the upper and imparting a finished appearance tothe upper at the point where it bends over the edge of the insole, itwill be apparent from the specific description hereinafter containedthat they are also capable of being used alone or in connection withother devices for acting upon the shoe upper, and it is accordinglyconsidered that a feature of the invention consists in the provision ofupper finishing tools arranged to act simultaneously upon the upper atopposite edges of the insole, and to automatically conform to thevarying curvatures of the edge of the sole.

In addition to the features of invention above referred to, the presentinvention also consists in certain devices, combinations andarrangements of parts hereinafter described and claimed, the advantagesof which will be obvious to those skilled in the art from the followingdescription.

Referring now to the drawings accompanying this application, Figure l isa view in side elevation of a machine for beating out shoe uppersembodying the various features of the present invention in theirpreferred form. Fig. 2 is a plan view with the belt pulley at the frontof the machine removed; Fig. 3 is a view in front elevation of the headof the machine; Fig. 4 is a plan view taken on the line 4-4 of Fig. 1;Fig. 5 is a plan view similar to Fig. 4 but show ing the parts in adifferent position; Fig. 6 is a plan view of one of the beating outtools removed from the machine; and Fig. 7 is an end view of the beatingout tool illustrated in Fig. 6.

The beating out tools are indicated at 1 and 2. As is clearlyillustrated in Figs. 6 and 7, each tool is triangular in shape so as topresent at its periphery a series of working surfaces in the form ofprojections or blades 3 which, as the tool is rotated, cleliver a seriesof blows upon the lower edge of the upper and pass over the upper with arubbing or wiping action. The beating out tools are mounted adjacent toeach other upon the inner ends of studs 4 and 5 and are removablysecured to bevel gears 6 and 7 mounted to rotate upon the studs 4 and 5respectively. Bevel gears 8 and 9 secured upon the lower ends ofvertical shafts l0 and 11 mesh respectively with the bevel gears 6 and 7and through these bevel gears a rapid rotation is imparted to thebeating out tools during the operation of the machine. hen in normalposit-ion, that is, when there is no work in the machine, the studs 4and 5 are in alinement with each other and the beating out tools are inclose proximity to each other as illustrated in Fig. 4. Then in thisposition the tools are adapted to act upon the edge of a shoe upper atthe rear end of the heel and beat out the upper upon the insole, thewiping action of the working surfaces 3 across theinturned edge of theupper also tending to pull the upper over the edge of the sole.

In order to enable the beating out tools to act tothe best advantageupon the upper at the sides of the heel the tools are moved outwardlyand their angular position with relation to the medial line of the shoechanged as indicated in Fig. 5. To allow the tools to be so moved thestuds 4 and 5 are secured in the lower ends of brackets or arms 12 and13 which are pivot-ally mounted upon a vertical stud 14 secured in anoverhanging arm 15 of the machine frame. The arms 12 and 13 extendoutwardly and rearwardly from the stud 14 so that the axes of the studs4 and 5 are located in a vertical plane at the rear of the vertical stud14. By reasonof this arrangement a swinging movement of the arms 12 and13 about the stud 14 changes the angular position of the beating outtools with relation to the medial line of the sole, and at the same timemoves the tools bodily toward or from each other. The shafts 10 and 11are mounted in the arms 12 and 13 and are provided at their upper endswith pinions 16 and 17. Upon the upper end of the stud 14 is mounted agear 18 which drives the pinion 17 directly and the pinion 16 indirectlythrough an intermediate pinion 19 mounted on the arm 12. During theswinging movements of the arms 12 and 13 the pinions 16, 17 and 19 movebodily about the axis of the stud 14 as a center and thus remain inoperative position with relation to the gear 18 so that the beating outtools are continuously rotated regardless of any swinging movementswhich are imparted to the arms 12 and 13. A continuous rotation isimparted to the gear 18 by means of a belt pulley 20 secured to thegear, which pulley is driven by a belt passing over guiding pulleys 21and 22 at the rear upper portion of the machine, and over a pulley 23secured to the driving shaft 24.

In addition to the beating out tools 1 and 2 the machine illustrated inthe drawings is also provided with upper finishingtools 25 and 26 whichas shown are in the form of rolls shaped to bear against the upper atthe edge of the sole and smooth and iron the upper. At their upper endsthese rolls fiare outwardly so as to fit snugly against the edge of theinsole and the counter portion of the upper. The rolls are yieldinglypressed toward each other and are thus allowed to move toward and fromthe medial line of the sole so as to conform automatically to thevarying curves of the sole. In addition to allowing thetools 25 and 26to conform automatically to the curves of the sole the movements ofthese tools toward and from each other are also utilized to change theposition of the beating out tools. To this end the tool 25 is mountedupon an arm 27 which is rigidly secured to a vertical pin 28 mounted torotate in suitable bearings in the frame of the machine, and the tool 26is mounted upon an arm 29 mounted to swing freely on the pin 28 as apivot. An arm 30 is rigidly connected to or made integral with the arm29, and is connected at its outer end by a link 31 to the swinging arm12. A similar arm 32 and link 33 connect the pin 28 and the swinging arm13. The tool 25 is thus connected to the arm 13 and the tool 26 to thearm 12 so that swinging movements are imparted to the arms whenever thetools 25 and 26 move toward and from each other. The arms 12 and 13 arenormally held in a posit-ion in which the axes of the studs 4 and 5 arein -alinement by means of coiled springs 34 and 35 connecting the armswith the frame of the machine. In order to cause the tools 25 and 26 andthe swinging arms 12 and 13 to move in unison and to the same extent,the arms 27 and 29 are provided with rearward extensions 36 and 87 whichare connected by links 88 and 39 to a horizontal slide 40 mounted toreciprocate in a guideway on the machine frame.

The shoe to be operated upon by the heating out and upper finishingtools may be presented to the tools while held in the hand of anoperator. To relieve the operator of this work, however, the machineillustrated in the drawings is provided with a shoe support or jackarranged to support a lasted shoe while being subjected to the operationof the tools. This jack consists of a sleeve 41 mounted upon the upperend of a rod 42 and provided with a last pin 43. The sleeve 41 isprevented from turning on the rod 42 by means of a pin 43 projectingfrom the rod through a slot in the sleeve. A spring coiled around therod 42 and interposed between a fixed collar on the rod and the lowerend of the sleeve 41 serves as a yielding support for the sleeve andallowsthe shoe to be depressed slightly during the action of the beatingout tools. The rod 42 is pivotally mounted at its lower end in the baseof the machine frame so that the shoe can be moved beneath the beatingout tools. A chain 45 connecting the rod 42 with the frame of themachine limits the outward movement of the rod.

The machine illustrated in the drawings and above described is designedparticularly for operation upon the upper at the heel portion of a shoe.The shoe is presented to the machine as indicated in Figs. 1 and 4, thetools 25 and 26 hearing against the upper at the rear end of the heel ofthe insole and the beating out tools engaging the lower edge of theupper and heating it out against the surface of the insole. As the shoeis forced toward the rear the upper finishing tools 25 and 26 areseparated, and simultaneously the beating out tools are moved bodilyaway from each other and their angular position with relation to themedial line of the shoe changed as indicated in Fig. 5. The workengaging surfaces of the beating out tools deliver a series of blowsupon the lower edge of the upper and wipe across the upper from the edgeof the upper toward the medial line of the shoe, so that the upper ispressed smoothly against the surface of the insole, and at the same timethe upper is stretchedtightly and smoothly over the edge of the insole,a permanent sharp bend being formed in the upper at the point where itpasses over the edge of the sole. Simultaneously with the beating outoperation the upper finishing tools 25 and 26 smooth and iron the upperat the edge of the insole and assist the heating out tools in impartinga neat and tinished appearance to the upper at this point. To assist theoperator in presentingthe shoe properly to the beating out and finishingtool a guide 46 is provided adjustably secured to a block 47 which issecured upon the lower end of the vertical stud 14.

The machine illustrated in the drawings may be used to beat out thelower edge of the upper upon an insole after the upper has been drawnover the last, but before it has been lasted over the insole, or, it maybe used upon the shoe after the upper has been lasted. In the lattercase the drawing action of the beating out tools upon the upper is lessmarked, but the movement of the working surfaces of the tools over theupper act in the same manner as when the beating out operation isperformed before the shoe is lasted to press the upper closely againstthe surface of the insole and to smooth and finish the upper at thepoint where it passes over the edge of the insole. The machine is alsoadapted for operation upon the toe portion of a shoe either before orafter the upper is lasted over the insole.
